I discovered a workaround to this problem. It is a bit annoying in use, but does work:

template<template <typename...> class T, typename... Args>
struct TypeJoin
{ typedef T<Args...> type; };

template<typename T1=int,typename T2=int, typename T3=int>
struct my_tuple {};

template<typename… T>
struct X
{
        // my_tuple<T…> tt; <- This won't compile.
        typename Join<my_tuple, T…>::type t;
};
